This presentation discusses developing Notepad++ in Java. Notepad++ is a simple text editor for Windows but can only run on that OS. By developing it in Java, it can now run on any OS with a JVM installed, allowing users of other systems to use the familiar Notepad++ interface. The presentation outlines key features like basic editing shortcuts and file support, as well as limitations like lack of formatting options. It proposes updates like search/replace, password protection, and removing file size limits to improve the Java version of Notepad++.
